Short answer: YEAP, it is centralized :/
The Ethereum network is transitioning into Proof of Stake. To participate in the network, one must run a validator node. These nodes are the source of truth for the system and can be run by anyone with at least 32 ETH and can set up the infrastructure needed. The popular option for most individuals who want to stake their ETH is through a staking provider. Staking providers offer hassle-free staking for users for a cut-off of their staking rewards.
Now here's a thought experiment for you
If the vast majority of a system's computations are being run by 4-5 companies, would you consider that system centralized or not? Because that is precisely the case for ETH 2.0 at the moment.
You can choose to not care about ETH 2.0 being centralized, but you can't ignore the fact that it is.
